- Added filter on load to help prevent potentially dangerous comment
HTML in DB at load time (if it gets passed input filtering, or is
existing).
- Added TinyMCE valid_elements for input wysiwygs, to gracefully degrade
content at point of user-view, rather than surprising the user by
stripping content, which TinyMCE would show, post-save.
- Moves guest user caching from User class to app container for
simplicity.
- Updates test to use simpler $this->users->guest() method for
consistency.
- Streamlined helpers to avoid function overlap for simplicity.
- Extracted user profile dropdown while doing changes.
- Updated mail notification design to be a bit prettier, and extracted
text to new lang file for translation.
- Added debounce logic for page update notifications.
- Fixed watch options not being filtered to current user.
- Adds option filtering and alternative text for page watch options.
- Adds "Watched & Ignored Items" list to user notification preferences
page to show existing watched items.
Kept existing "COMMENTED_ON" activity for upgrade compatibility,
specifically for existing webhook usage and for showing comment
activities in activity lists.
Precursor to content notifications.
Currently untested.
Also applied some type updates.
